To all whom it may concern:

Be it known that we, FRANCIs E. STANLEY and FREELAN O. STANLEY, citizens of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Burners for Steam-Generators, of which the following is a specification.

()ur invention relates to that class of vapor burners used with boilers for generating outline the burner casing, the boiler in dotted lines, and the construction and arrangement of Vaporizers, pipes and adjuncts embodying our invention; Fig. 2 is a sectional plan of the Vaporizers.

The details of the burner are not shown. as any suitable burner may be used, the arrangement illustrated being that used with a burner having a pilot light supplied from a separate nozzle from that supplying the main burner.

The main vaporizer 1 is shown in the formof a tube, but it may be of an y required construction, communicating at one end with. a pipe 2, the flow of liquid fuel to which from the main supply pipe 3 is controlled by a valve 4. A prelin'iinary heating of the oil is secured by interposing a coil 5v between. the main supply pipe 3 and the valve 4, said coil being arranged above the boiler A so as to be heated by the products of combustion passing from the boiler. By this preliminary heating of the oil, the vaporizing action in quickcned while the coil constitules an. extended heating surface, which will be heated by the air flowing up through the boiler tubes and the oil will be heated thereby when the motor is at rest. The

vaporized mmdition oi the oil. is thus mainthe boiler even it the main burner in the casing l, is not tained for a time by heat from lighted.

The vaporizer comnnuucates at one end with a nozzle 6 troni which vapor is injected into the nixing tube 7 of the main burner.

it is not infrequent that from the use of a poor quality oi" oil or other causes, carbon is deposited in the vaporizer and the necessity of removing the vaporizer, disconnecting the attachments, etc, involves ob iwtionable labor and consun'iption of time, while also putting the whole apparatus out of use. To avoid these diiiiculties we connect the pipe with the side of the vaporizer, and insert in the end of the vaporizer detachable screw plug 8, the removal oi which permits ready access to the interior to clean the same, this operation being facilitated-by providing an opening coinn'iunicatingwith the opposite end of the vaporizer, which is closed by a (lo-- tachable screw plug 9, so that said plug can be removed and the end of the 'llexiblc tube of an air pump may be attached, and a forcible blast of air passed lengthwise through the vaporizer, carrying all particles out of the opposite end. i To further facilitate the cleaning oi the vaporizer, it may contain a scraper it) in the form. of a rod with wire woinid spirally around it. 'lhe'plug 3 is made with a recess so that the end oi the scraper, when the plug is in place, may extend. into the same but project beyond the end of the vaporizer to be readily seized by a pair of pincers when the plug is removed. There is a pilot ligh t which is supplied with a burning mixture trom a nozzle 13 arranged opposite a supplemental. mixing tube 12, and the vapor is supplied to the latter from a separate wiporizer 1%, and.

we place this second vaporizer in such close' proximity to the main vaporizer l, that both will be heated simultancously, but it there is no oil in the vaporizer 13) the heat cxtnwtcd in vaporizing the oil in the vaporizer l t will so reduce the temperature ot the main vapo iizor that it will notburn out.

The two Vaporizers may consist ot a bar with two channels bored longitudinally through the same orot two parallel tubes brazed. together.

"he supplemental vaporizer may be providcd with end openings closed by detach able plugs and scraper to! cleaning as inv the base oi the main vaporizer.

By the use oi an independent 'aporizer with the pilot light nozzle the. latter is sup-- plied with vapor from its own vaporizer and El l) it is possible to run the pilot light part of the burner independently of the main burner or its vaporizer in every respect. e

A esirable construction "is that shown where a casing C has two branches 15, 16, each with a nozzle and connected with both Vaporizers. This avoids en objectionable number of joints and facilitates manufaoture.

The vaporizer 14 communicates through a ipe 17 with a valve casing 18 to which oil fiows through a branch from the main supply tube 3, and the stems 19, 20 of the valves controlling the flow to the va orizers extend through the side of the vehic e and are pro vided with suitable external handles so that the driver can manipulate them from the seat with facility.

Without limiting ourselves to the construction shown, We claim as our inven tion l. The combination with a burner having a plurality of independent mixing tubes, of a plurality ofiindcpendent Vaporizers arranged in close contact side by side to permit the seaees conduction of heat from one to the -other for the purpose set forth.

2. The combination with a vapor burner,

mixing tube and nozzle for supplying the' burner with a mixture of vapor and air, of a supplemental mixing tube and nozzle, and mdeendent Vaporizers supplying the two nozz es independently, and arran ed in close in testimony whereof We have-signed our names to this specification in the presence of two subscribing witnesses.
